Process and system for managing an interruption of a broadcast of a sonorous message in an aircraft

Abstract

A method for managing an interruption of emission, in an aircraft, of an acoustic message including an information item about a state of part of the said aircraft and/or about its environment, wherein the acoustic message is structured into one or more successive acoustic fragments each representative of the information item, the method includes the steps of: delaying, starting from a given moment, the execution of a decision to interrupt the emission of the acoustic message until the end of emission of an acoustic fragment that is in the course of emission at the given moment; and executing the interruption decision.

1. A method for managing an interruption of emission of an acoustic message produced in an aircraft, the method comprising:
 having available the acoustic message that includes an information item about a state of part of the aircraft and/or environment of the aircraft and that is structured into one or more successive acoustic fragments so that each acoustic fragment is representative of the information item; 
 delaying, at a moment when a decision to interrupt the emission of the acoustic message is registered, execution of the decision to interrupt the emission of the acoustic message until emission of an acoustic fragment of the acoustic message that is currently being emitted is completed; and 
 executing, by a controller, the decision to interrupt the emission of the acoustic message, thus interrupting the acoustic message that is currently being emitted. 
 
     
     
       2. The method according to  claim 1 , wherein the acoustic message is a first acoustic message, and the decision to interrupt the first acoustic message is made as a function of reception of an information item defining an alert condition, the method additionally comprises, after the step of executing the interruption decision, activating emission of a second acoustic message corresponding to the alert condition. 
     
     
       3. The method according to  claim 2 , wherein between the step of executing the interruption decision and the step of activating emission of the second acoustic message, delaying activation of emission of the second acoustic message. 
     
     
       4. The method according to  claim 2  or  3 , wherein the information item defining an alert condition is updated regularly, the activation of emission of the second acoustic message is effected if the information item defining an alert condition is valid at a moment situated after the end of the step of executing the interruption decision. 
     
     
       5. The method according to  claim 2 , wherein the interruption of emission of the first message is effected by a system known as an interruption system, and emission of the second message is effected by a system known as an emission system, the method additionally comprises:
 before the step of delaying execution of the interruption decision, transmitting, from the emission system to the interruption system, a command to interrupt the acoustic message, and 
 after the delaying step and before the step of activating emission of the second acoustic message, transmitting from the interruption system to the emission system, an authorization to emit the acoustic message. 
 
     
     
       6. A system for managing an interruption of emission of an acoustic message produced in an aircraft an, the system comprising:
 the acoustic message that includes an information item about a state of part of the aircraft and/or environment of the aircraft and that is structured into one or more successive acoustic fragments so that each acoustic fragment is representative of the information item; and 
 a controller configured to
 delay at a moment when a decision to interrupt the emission of the acoustic message is registered, execution of the decision to interrupt the emission of the acoustic message until emission of an acoustic fragment of the acoustic message that is currently being emitted is completed, and 
 
 execute the decision to interrupt the emission of the acoustic message, thus interrupting the acoustic message that is currently being emitted. 
 
     
     
       7. The system according to  claim 6 , wherein the acoustic message is a first acoustic message, the management system additionally comprises:
 means for comparing a priority attribute associated with an information item defining an alert condition with a current priority threshold associated with the first acoustic message, the comparison means being capable of modulating how a decision to interrupt the first acoustic message is made, and 
 means for activating emission of a second acoustic message corresponding to the alert condition. 
 
     
     
       8. The system according to  claim 7 , further comprising:
 means for delaying activation of emission of the second acoustic message. 
 
     
     
       9. The system according to  claim 7  or  8 , wherein the information item defining an alert condition is updated regularly, the system is additionally provided with means for modulating the emission of a second acoustic message by the fact that the information item defining an alert condition is valid at a moment subsequent to execution of the interruption decision. 
     
     
       10. The system according to  claim 7 , wherein interruption of emission of the first message is effected by a system known as an interruption system, and emission of the second message is effected by a system known as an emission system, the management system additionally comprises:
 means for transmitting, from the emission system to the interruption system, a command to interrupt the acoustic message, and 
 means for transmitting, from the interruption system to the alert system, an authorization to emit the acoustic message.
